* xterm.c (XTread_socket): When we get MapNotify, UnmapNotify,

	Expose, ExposeWindow, or UnmapWindow, set f->async_visible, not
	f->visible.
	(x_do_pending_expose, x_raise_frame, x_lower_frame,
	x_make_frame_invisible, x_make_frame_visible, x_iconify_frame):
	Test and set f->async_visible and f->async_iconified, not
	f->visible or f->async_iconified.
